On the BC branch, in link.cc, there are a number of
places where we use _Jv_Malloc where we ought to use
_Jv_AllocBytes. Search for the FIXME comments
(not every malloc needs to be replaced).
Actually doing this results in a buggy runtime, however.
There is probably some GC marking problem, however boehm.cc already
appears to mark the needed fields, so the exact problem
remains unknown.
